immediate effect of johnstone's pressure splint added to stretching on the spasticity in cerebrovascular disease.

Conditions: Spasticity as Sequela of Stroke

Summary: title: immediate effect of johnstone's pressure splint added to stretching on the spasticity of elbow flexors and wrist in cerebrovascular disease (cvd). introduction: in the rehabilitation of the upper limb post-cvd to employed exercise modalities such as stretching (s) to control spasticity, improve mobility and functionality. also it is used the johnstone´s pressure splint (jps), which exerts circumferential pressure and contribute to spastic pattern inhibition, sensory re-education and increased of the mobility. objective: the aim of the study is to evaluate the immediate effect of jps added to s on the spasticity of elbow flexors and wrist, the reflex excitability and the joint kinematics in stroke. materials and methods: a randomized experimental study with two intervention groups will be performed. control group (gs): stretching and experimental group: (gjps + s): jps plus s. measurement times: before the intervention (t0) and immediately post- intervention (t1). the outcome variables are muscle tone of elbow, wrist and hand assessed with the modified ashworth scale (mas); h reflex of the flexor carpi radialis muscle, latency (ms), duration (ms) and amplitude (mv) of the m and h waves, and the amplitude the hmax / mmax ratio (%). shoulder, elbow and trunk angles (degrees), trunk displacement (cm) and duration (sec) of the functional reach pattern (paf) will be evaluated with the software contemplas. analysis: descriptive statistics will be applied and shapiro wilk test to evaluate the normality of the variables. intra-group differences will be assessed with the student t-test paired and intergroup with the student t-test unpaired or the sum of wilcoxon rank according to the distribution of the variables. expected results: hypotheses and contributions to the scientific evidence on the immediate effect of the s and jps will be generated, to support the jps as a complement to the traditional treatment. the results will be socialized in an international scientific event and a publication will be submitted to an impact journal. key words: spasticity, h reflex, johnstone's pressure splint, stretching, functional reach.
